A surface coupling model, able to generate intermediate structures in the nucleon-nucleus scattering is dealt with. Particular emphasis is given to the case of several interfering resonances, with the aim of reconsidering, on the grounds of a physical model, the R- and S-matrix approach to the problem.

Abstract
A surface coupling model, able to generate intermediate structures in the nucleon-nucleus scattering is dealt with. Particular emphasis is given to the case of several interfering resonances, with the aim of reconsidering, on the grounds of a physical model, the R- and S-matrix approach to the problem. In the case of two interfering levels, the pole collision has been investigated by variation of some meaningful parameters of the model. Some examples of actual cross-section analyses are finally given.File in questo prodotto:
